I have check the x5World bluetooth compatibility pages (thanks UCrewX5!).

Ideally, I want a CDMA bluetooth phone which can transfer address book info into the X5. Looks like I have two choices :

1) go for the hard to find SE T608 (rangerfan had good experience); but not sure that the text messaging works on Verizon. I need text messaging.
2) Mot. 710 (and hack its software, yikes)

Not much of a selection

I have a further Q for the bluetooth experts. Since the standard issue V710 does not transfer the phonebook; can you manually add phone #s to the X5 address book and then make use of the nav. screen dialing and voice dialing ?

Thanks for any input.
